Why spend valuable free time with family learning something that you will possibly never ever use. Learn something when its needed and save wasted time learning something that's never needed.
Because it is fun, and it is what causes us to move forward in our professions.
Its not as fun as spending time with family. We all have our own needs from life - personally time with loved ones is top priority over learning things I may never use.
So you have absolutely no personal time where you work on hobbies, etc? That's what most are talking about here. When others might be off playing basketball, others will be playing in a lab, learning - because that's what they enjoy doing more than playing basketball.
Pretty much this. My home lab is a hobby for me. I like seeing how technology works and how it can be applied in the "real" world.

Of course. But learning a random arbitrary IT 'thing' has no use unless that thing is needed - say at work. If that's the case, work has a responsibility to engage end provide that time, not me.

Why does one come at the cost of the other? I've always found them to go hand in hand.
Now, as in my basketball example, I don't find I agree with Scott here at all. Education takes time away from anything else you're doing unless the family is learning the same thing as you at the same time. I'm not really sure how Scott gets more time with family because he spends time getting educated.
The only thing I can think is that he's robbing Peter to pay Paul. i.e. he spends time now self educating, and then later he will already have that education when decision time comes, so he can make a fast decision then, and return to the family faster at that future point.

I have a laptop, but no real home lab. I have done the odd thing I've been really interested in, but not often.
IMO, if I need to learn something for work - I learn at work/on the job.
If I don't need to learn something 'IT' for work, i'm most likely not going to spend time learning it at home - I have no use for it.^ of course, at the point it is needed for work, if, then I will learn at work as its needed.
Why spend valuable free time with family learning something that you will possibly never ever use. Learn something when its needed and save wasted time learning something that's never needed.
Because you are genuinely curious and passionate about technology? I will probably never use KVM on the job but I would like to know how to do things in it if I ever do need it. Many technologies that I implemented in my home lab I have brought to my job as a resource.
Also, as IT, we make decisions about what to use on the job. How do you know what to use at work, if you haven't been playing with it?
Research when a project comes up.
That's an insanely costly and ineffective means of doing it most of the time. I have to make decisions constantly, often in a meeting. There is no time to research, especially if I have to question things already proposed. Researching might take weeks or months and in some cases years. Decisions often have to be in minutes.
Yes, but using my OWN time to learn to is a detriment when all it does is save the COMPANY time. Sure, give me 'research days' to do this stuff or an allowance. But don't expect me to learn everything possible to learn in case 'something' comes up and needs a quick answer.
Research such things at work, for work. Home is for home.
No, you've missed the point - it's not about work vs home - it's about improving yourself. Does that benefit your company? of course, but does it benefit you more when it's time to find another job - hell yes it does.

YAGNI.
That's a good principle, but doesn't apply to education
Heh, indeed. Although, it somewhat does. If i'm not going to need it, its not useful to learn. If a job requires it, at that point i'd spend time learning it - quite possibly in my own time. But before then, no point.
What if you couldn't get the job without already knowing (or at least having a basic understanding of) it?
At THAT time i'd either learn this, like I did say, or not apply.
So you are agreeing that you'd use a home lab and self education, but only if you pre-determined to make a specific job leap? So basically always staying in the same position, not proactively preparing for changing jobs and not exploring other areas that might be of interest?
Nothing wrong with that, but it seems very risky to be focused so much on the reliability of a single, current job both because you are employer dependent and because you are technology dependent and because it means that there is little upward mobility. Maybe you love where you are, nothing wrong with that, the industry needs more people that find what they love and don't explore other avenues that they won't like as much. But most people don't get there until late in their careers.

It's to late to learn it then.. they are hiring now - it might take you months or years to learn it.. by then the job is long gone.

It's not about saving your company time, it's about making you able to do the job, versus the job not getting done or someone else doing it.
Home is for home, and work is for work, is exactly what, as someone wanting maximum family time, I want to avoid. I want home and work to mix as much as possible, because I never want to be without family time.

Because it allows me to work in more "Decision making" roles rather than "button pushing" roles. And it gives me more senior positions. So that I have the power to do things like dictate my schedule, my location, that I will work from home, that my family will come with me on business travel, and so forth.

I did say I've done that for the odd thing I've been interested in... but not often enough to call it a lab.

Right. This was never said (or even implied) but other people not on this thread have said this to me this past week and it is worth bringing up - they basically hate this jobs and want it to go away at the end of the day. That makes zero sense to me. That family comes over work - I think you'll find no one that agrees with that more than me. Every job decision I make is about how it will impact my time with my family. But after spending time with my family, doing my job is my favourite thing to do. Sure, even then, I still want to watch TV sometimes or play video games, but not as much as I want to work. And I often do them all at the same time.
If you dislike your work, find a job you love.

Like "Exchange Admin" not "Exchange Admin for COmpany Y"

Percentage wise, I think the number of these types of jobs are pretty small. So while it's definitely great that you made it there, the reality is that many/most never will. That's not saying that they couldn't if they really wanted it. According to you, there is a vacuum in that space, not enough people to fill the need, but you're also talking about a type of person that is needed for those positions, which is also a rare thing.

I don't need a lab to enable me to have enough of an overview to be able to make decisions. A lab enables me to know something inside and out with enough time give, and IMO, no point going in such depth unless its actually needed.

Then how will you ever progress? If you are a Windows desktop support person how do you move up to network engineer? Most companies won't educate you on that so you can get a job at that company doing that... you have to self learn at least the basics... then show them you know it to get a promotion, or move to a new company with certs showing you at least know basics... etc.
You don't just wake up tomorrow and have a job supporting VMWare clusters when yesterday you only knew about Windows desktop machine support. -

Well, for example, in the SMB, it's really the only needed role. Basically anyone choosing to work in the SMB is either the person in that role or working directly for the person in that role almost always as the sole adviser. I bet the majority of IT roles are either decision maker or the key decision influencer roles.

One explains the other. The vacuum exists due to a lack of people prepared to do those roles.
